The Common Kestrel (Falco tinnunculus) is a small diurnal bird of prey recognisable by its distinctive hovering flight, often referred to as "windhovering". Its presence is synonymous with biodiversity and natural balance—fundamental values at Château Cazebonne. It is an essential link in the vineyard ecosystem, acting as a vigilant sentinel over our parcels.

This raptor is distinguished by its elegant silhouette, its spotted rufous plumage in females, and its grey head in males. Its wingspan generally ranges between 65 and 80 cm, with a weight fluctuating between 150 and 250 grams. Its powerful talons and hooked beak are perfectly adapted to capturing prey. Its piercing gaze, characteristic of predators, allows it to detect the slightest movement on the ground.

The Common Kestrel is present year-round in the Cazebonne vineyard. It typically nests in tree hollows, rock crevices, or specially installed nesting boxes. Its breeding season runs from spring to summer, during which the young are fed by the parents with prey hunted in the surrounding area. The visibility of the adults peaks when they hunt for their brood, intensifying their flights back and forth across the vines.

At Château Cazebonne, this bird is frequently observed soaring above our grassed cover crops and hedgerows. These habitats, rich in biodiversity, provide an ideal home for its prey. The vast expanses of the vineyard, interwoven with natural areas, offer prime vantage points for its daily hunting. Our commitment to thriving biodiversity and living soils directly encourages its presence.

The ecological role of the Common Kestrel is fundamental. It serves as a natural regulator of small rodent populations, particularly voles, which can damage the roots of young vines. By preying on these pests, it helps maintain vine health without relying on chemical treatments. Its diet also includes large insects, such as grasshoppers and crickets, thereby offering a dual benefit against potential vineyard pests. This species fits seamlessly into our agroecological approach.

The interaction between the Common Kestrel and the vineyard is clearly beneficial. By curbing rodent proliferation, it protects our young vines from root damage. Its presence is an indicator of the sound environmental health of our parcels and the effectiveness of our nature-friendly viticultural practices. Alongside other raptors and birds, it is a valuable ally to the winegrower.

The presence of the Common Kestrel is a daily source of satisfaction at Château Cazebonne, reflecting the restored balance of our ecosystem. Observing it hover above our vines bears witness to the success of our conversion to organic farming in 2017. This approach creates a healthy environment for flora and fauna, enabling species like the Common Kestrel to thrive and fully play their role as natural regulators. It is a tangible illustration of our commitment to preserving the natural and viticultural heritage of Bordeaux—a quest for authenticity and uniqueness made possible by the steadfast support of wine lovers who enjoy our wines and share our vision; you can explore this subject further via the book "Bordeaux, une histoire de cépages" available as a digital download, or test your knowledge, before discovering all our cuvées on the Cazebonne online shop.
